i had tein hr coilovers with 15X8 welds with 275/60/15R nittos drag radials at 12 psi, anit lag and 400whp. the car is a s13 hatch.

now its all the same but i have stock shocks and springs. my best 60' is 1.89 on the coilovers and 1.73 on the stock shit. im getting new m/t et streets very soon. what else can i do to lower my 60'?
coilovers again? adjust something? any help is good.

lower the new et streets down to 11psi.. you should break a axle or the tranny if they are still stock...

install subframe spacers.. and maybe go auto, if you have the money..

i no longer have the coilovers. i have no sway bars. my susp. is completely stock. i have the anti lag set perfect for the way it sits now. i know that i need new tires. i was looking at sub frame bushings and spacers and staying with the stock shocks and springs

You should've kept your coilovers and bought new springs and then had them revalved for drag. Tein will revalve them for around $100 per shock. I'd def get some subframe spacers. What is your alignment like?

i have dds axles and a 300zx/mazworx trans. my drivetrain is good for over 600hp all around.

i was thinking of getting subframe spacers. they are to get rid of the wheel hopping right?

they will help for sure..

o yeaa put your alignment to 0.. and put the et streets to 11psi..

the tires you are running right now suck!! get a 26-10.5-15 et street..

You gotta tell us what you have so we can tell you what to improve. LSD? Motor mounts? 1 piece axle? All that stuff would help tremendously. A list of what has been done in this situation would be ideal.

i know i need new tires. the nittos blow and are shot. but even when they were good my 60' was 1.7. i am getting the m/t et streets. i also am going to get subframe bushings and spacers. ill look into the hks drag suspension.

anything else recomended? i do need a front end alinement. do they do the back too?

if you wanna adjust the back your gonna have to get adjustable ruca's and basically replace traction rods n stuff in the rear so they can become adjustable.

i say screw the spacers get solid mounts for your subframe. more likely your stock bushings are welldone. also do solid/polyerethane bushings for your suspension. possibly a short shifter would help (i cant tell if you have auto or manual 300zx trans)

test and adjust the gearing (rear end) also thats more proportionate to your setup.

its a manual trans. i have a short shifter. im just looking to lower my 60' i have mph. i trap 120mph. i could trap higher but my tire presure has to be really low to get out the hole. so thats basicly my whole goal is to get the best traction with the max amount of tire pressure so i dont have to sacrifice so much top end.

btw best run was 1.73 60' 11.74 @ 118 mph. i have trapped 120 but my tire pressure was at 15. those runs it was at 9psi

Soft springs/struts out-back and run the opposite up-front. Adjusting the rear camber to zero would increase the amount of rubber on the track as well. I would also suggest getting anti-squat bushings, I know I've seen them somewhere for the S-chassis.

btw best run was 1.73 60' 11.74 @ 118 mph. i have trapped 120 but my tire pressure was at 15. those runs it was at 9psi

damn... jeff(nismoknight) can correct me if im wrong but i believe a local (cerio) ran a 10.7x with around 400hp(pistons,2871, z32 trans, etc) im not sure what tire he runs i think he runs et streets. maybe jeff could chime in and help out. you should be running better times.

Yes and no. Too much of it can hurt camber angles and take away traction. Not enough squat will induce wheel spin, you have to find the perfect median. Like I said I think someone sells ones you can adjust, I.e. add a spacer and take away one to dial in the perfect setup for your car.

i drive my car on the street with my welds on it. so i have to go with a street tire. i would love to do a slick but ill get pulled over every 5 minutes instead of 10.

that 240 with 400 that went 10, what tires he running, psi, car weight? those all play a factor too. too low of a psi like i have to run now with my nittos kills my mph. from at 9psi my mph was 116 and at 12psi it was 119

not 10.7 but yes he was in the 10s.. hes on a full slick.. and about running better times, it all depends on the track/weather/tires/shifting/boost/ect..

Because et streets are the same as slicks almost.. just street legal and they do not grow.. best street/track tire..

Just get the et streets.. its simple..

That 240 has slicks.. and is max psi for a gt2871r..

dude mph doesn’t matter really.. My s13 went 10s with 116mph... Worry about the car hooking first and then worry about mph..

i was at the track on nov. 4th for imports vs. domestics and mickey thompson had some 275/60/15's on sale so i got them mounted at the track. turned my anti-lag to 5k, tire presure at 16psi and heated the tires up a little bit. launched the car and BOOM broke my dss 600whp axle. no wheel hop, just saw the front come up and down real fast. i moved a total of 7" off the line. haha i found traction. so now i have to get it repaired and try again next season with my 600whp set up im doing in the off season. also i have to roll the rear fenders for the tire to fit.

if you're at 400whp in an s13 shouldnt you be trapping in the mid 120's.

i put down 350whp on a mustang dyno which is like 400 on a dyno jet. depends on who you ask for numbers. i think it might be the trans geared differently. i had a dog box and trapped a best of 11.90 @ 120 and with the 300zx trans i run now i trap [email protected]. same mods. only changed out the trans. tire pressure was lower on the 11.60 at 10psi and was at 14 with the dog box.
